Not sure that any of that translates as "Your dates on AZ are incorrect", nor am I sure why per capita numbers have made an appearance given that wasn't what was said either.
Even if we had only been at just those 1.8 million you mention who we know could have been fully vaccinated by February 8th - which as a reminder for everyone else is around 1.2 million more elderly and extremely vulnerable people fully vaccinated than we did have by that point - we'd be third in terms of actual numbers of people fully vaccinated.
Moreover if Pfizer only rolled out at the level you cite for the first month of the programme (so another 1.8 million people given Pfizer first jabs in the month from January 8th to February 8th), that is still an extra 450,000 who'd we'd expect to have had their second Pfizer by February 8th (given the 21 day dosing schedule). That would put us just above Israel, into second in terms of overall numbers given a second dose.
As I said earlier, I think that is an under-count of what we could have potentially been at anyway because of how the vaccination programme ramped up from the start of January onwards.
